Vanhu havasi ivo chete vapenyu vanogadzira mahormone. Zvakare mhuka nezvirimwa zvine kugona uku. Imwe yeakakurumbira uye anoshandiswa zvakanyanya mahormone emiti ndeye ethylene, avo mafomu akasiyana.
Kana iwe uchida kuziva zvakawanda nezve ichi chirimwa kemikari, ini ndinokurudzira kuti iwe uenderere mberi kuverenga ichi chinyorwa. Isu tichataura nezve chii chinonzi ethylene, ndeyei uye kupi kwekuiwana mune zvakasikwa. Uye zvakare, isu tichakurukura kuti ndeapi michero isingafanirwe kuunganidzwa mudura redu kana mufiriji nekuda kweethylene.
Chii chinonzi ethylene uye ndechei?
Kune mahormone akasiyana siyana uye kwete muvanhu chete, asi zvakare mumhuka nemumiti. Ethylene, semuenzaniso, ihormone yemiti iri muchimiro chegesi. Chinangwa chayo ndechekuti gadzirisa maitiro anoenderana nesescence uye kukura maruva nemichero nemiriwo. Naizvozvo, inozivikanwawo semuti wekukwegura kemikari.
Kana gasi iri rakwira, miriwo iyi inokurumidza kuibva, iyo inoguma ichikonzera kurasikirwa kwemhando uye kuderera kwehupenyu hwayo hunobatsira. Zvakare, kune mamwe mahara utachiona mumhepo ayo anogona zvakare kukanganisa mhando yemaruva, michero nemiriwo, uye izvo zvinowedzera kuwanda kwavo kana paine ethylene munharaunda. Neiyi nzira, zvinomera zvinoparara zvinodzikira.
Kana iri yekushandisa ethylene, kune zvakawanda zvinoshandiswa zvehomoni iyi. Inowanzoshandiswa mumapurasitiki, kupfeka, zvinonyungudutsa, uye antifreeze. Iko kushandiswa kunopihwa zvakanyanya kunoenderana nekomboni. Ngatione mimwe mienzaniso:
- Polyvinylchloride: Lining yemadziro, pasi, pombi, matangi, nezvimwe.
- Polyethylene: Machubhu, mapaipi, madhireni, midziyo, zvikamu zve thermoformed, kuputira, nezvimwe. Icho chinhu chinoramba uye chinoshanduka.
- Polytetrafluoroethene: Gaskets, bushings, cookware liners. Iyo inozivikanwawo seTeflon.
- Polyacrylonitrile: Kugadzirwa kwemicheka yemachira. Iyo yakasimba uye yakapfava kudhaya mukomboni iyo inogona zvakare kurukwa.
- Ethylene oxide: Makemikari epakati mukugadzirwa kweasina-ionic sipo, ethylene glycol, polyethylene glycols uye zvigadzirwa zvavo. Iyo inoshandiswawo se fumigant. Iyo isina ruvara, inogona kutsva uye inofamba mvura kana gasi.
Ndekupi ethylene inowanikwa mune zvakasikwa?
Sezvatakambotaura, ethylene ihormone inogadzirwa nemiti. Ose maruva nemichero nemiriwo zvinhu zvipenyu zvinoramba zvichifema kunyangwe mushure mekukohwa. Kana vachifema, vanogadzira kwete chete carbon dioxide (CO2) nemvura (H2O), asiwo ethylene (C2H4).
Kana zviri michero nemiriwo, mhedzisiro mhedzisiro yeethylene dzakasiyana siyana. Pakati pematanho ekutanga ekuvandudzwa kwemichero nemiriwo, vane zvinhu zvine muchetura zvinonyangarika kana zvaibva. Naizvozvo, nekuda ethylene vanova dzinodyiwa. Uye zvakare, inopfavisa magadzirirwo ayo. Iwo mazinga e starch uye asidhi zvinoderedzwawo, nepo huwandu hweshuga huri kuwedzera. Nenzira iyi michero nemiriwo zvinova zvinonaka. Imwe pfungwa yekucherechedza ndeyekuti ino hormone inovandudza ruvara rweganda uye hwema hwavanopa.
Nekudaro, mushure mekutora michero nemiriwo panguva yavo yakanaka yekukura kwekushambadzira, zvese izvi zvinobatsira zve ethylene hazvisisina kunaka. Kana michero yasvika pakukwana kwakaringana, vanoramba vachigadzira iyi hormone, iyo inopedzisira yavakonzera kukwegura kusvika vaora.
Ndeapi michero isingafanirwe kuunganidzwa?
Kuva gasi, ethylene inoramba iri munharaunda. Kune michero uye miriwo inomira kuve huru vagadziri vehomoni iyi, nepo vamwe vachinyatsoitarisira. Mhando mbiri idzi hadzifanirwe kuiswa pamwechete, kudzivirira boka repiri kubva mukutsikira nekukurumidza. Kana muchero watoibva watoburitsa ethylene, kuibva kwemichero yakaukomberedza kunowedzera. Nenzira iyi vanotanga kuora nekukurumidza zvakanyanya kupfuura zvakajairwa. Mimwe mienzaniso yeiyi ingave inotevera:
- Makarotsi: Ivo vanowana kuravira kunorwadza.
- Asparagus: Mashizha awo anowedzera kukasira.
- Lettuce: Hutsvuku mavara anoonekwa.
- Broccoli: Inorasikirwa neruvara.
- Madomasi Ripe Greens: Dzinova nyoro.
- Mbatatisi: Ganda rinounyana uye rinotanga kuora.
Pane kudaro, mimwe michero nemiriwo zvinomiririra kugadzira yakawanda ethylene. Naizvozvo, ivo havafanirwe kusanganiswa neavo vataurwa pamusoro. Tichaona pazasi runyorwa rwemichero inogadzira yakanyanya ethylene gasi:
- Avocado
- Onion
- Plums
- Apple
- Mango
- Meloni
- Banana
- Madomasi
- Mazambiringa
Iwe unodzidza chimwe chinhu chitsva mazuva ese. Kana iwe wanga usingazive chinonzi ethylene, ndinovimba ndakajekesa uyu mubvunzo. Uye zvakare, zvinoshanda kwazvo kuziva kuti ndeapi michero nemiriwo zvisingafanirwe kuiswa pamwechete kuti zvigare kwenguva refu zvichitsva uye zvinonaka. Nenzira iyi tinochengetedza mari shoma patinenge tichitenga uye isu tinochengetedza mabhenefiti ayo miriwo inogona kutiunzira kwenguva yakareba.
